Steel rail ultrasonic flaw detection vehicle

Abstract

The invention relates to a steel rail ultrasonic flaw detection vehicle. The steel rail ultrasonic flaw detection vehicle comprises a flaw detection mechanism, a water tank and an industrial control host; the flaw detection mechanism comprises a detection frame, wheel type probes, a wheel type probe stepping motor and a coupling agent spray pump; the detection frame is provided with land walking wheels and a pre-mounted encoder guide wheel; the portions, corresponding to the two sides of the railhead, two sides of the rail web and the rail top, of the detection frame are provided with the wheel type probes respectively, and each wheel type probe is provided with a coupling agent spray head; the coupling agent spray heads are connected with the coupling agent spray pump through pipelines, and a spray coupling agent is sprayed onto the surface of a steel rail under the compression of the coupling agent spray pump; the detection frame is also provided with a spray switch of the spray heads; the water tank is fixed to the upper portion of the detection frame, and one side of the water tank is provided with a water injection port used for adding a flaw detection coupling agent. The steel rail ultrasonic flaw detection vehicle has the advantages that the use is convenient, finding of the rolling defect of the steel rail is facilitated, the defects in the manufacturing process of thesteel rail can be comprehensively and effectively detected, and the detection accuracy and efficiency can be effectively improved while the labor intensity is reduced.

Description

technical field [0001] The invention relates to the technical field of rail flaw detection, in particular to an ultrasonic flaw detection vehicle for rails. Background technique [0002] At present, the domestic rail ultrasonic flaw detection vehicle, the probe is only arranged on the rail tread, this flaw detector mainly detects rail transverse fatigue defects and screw hole crack defects. The rolling of the train is relatively smooth, which can ensure good coupling of the ultrasonic probe. However, the surface of the rail used by the turnout manufacturer is relatively corroded. Ensure that the ultrasonic probe is effectively coupled with the rail head and both sides of the rail waist, which will affect the effectiveness and reliability of the detection. Contents of the invention [0003] Aiming at the problems existing in the above-mentioned background technology, the present invention proposes a structure design that is simple, reasonable, and easy to use, which is con...
